I Built a Life Exchanger!

Two people who both wanted to commit suicide met on the edge of life and death, exchanged lives through a mysterious box, and began to use each other's bodies to survive. Lin Shen used Su Nian's body to face a half-white mother, a dead father, a coma who had an "accident" on the engagement night, and an ex-boyfriend who is still looking for her - a huge photo of her hung on the wall, but he couldn't tell what happened that day. Su Nian used Lin Shen's body to live in that windowless rental house, facing a debt of 47,000 yuan, a flat battery car, and family members who never cared about life and death and only called to ask if the salary was enough. They agreed: use each other's identity to survive for each other. But secrets surfaced one after another. Why did Su Nian appear on the rooftop wearing autumn pajamas? Her last words before she fell into coma were "I'm tired." What exactly was she tired of? What did that ex-boyfriend named Zhou Hang do on the engagement night? Why did Lin Shen's missing father suddenly appear at the door of Su Nian's ward? And where did that wooden box come from? Why did you choose them? When the two lives were completely exchanged, and when the truth of the past was revealed bit by bit, they discovered—— Sometimes, living is harder than dying. Sometimes, the trust of a stranger is warmer than that of a relative. Sometimes, what is exchanged is not only life, but also destiny.
